I have about 65 white switches going and after figuring out my network router channels everything has been rock solid for about 6 weeks or so.
However, over the last week I have had 2 switches become “Unavailable” . Does anyone have best practices to get them going again? Or should I just do a factory reset on both of them and then get them reconnected? Does it cause an issue with the switch to do multiple factory resets on them. Just curious if anyone else has any insights.
Power cycle them by pulling the air-gap switch below the paddle.
What border router are you using?
I had a lot of problems when I used to use Google Nest Border WiFi Pro 6e as my border routers - if that is what you have, also try restarting (power off / on) those. Apple TV is a much more reliable border router.
